This is how S ended up at walmart, Wallahu Alam!
N had taken these shoes out for donations and these were by the door. Hubby was making a late-night-quick-trip to Walmart and S wanted to join him. (in her PJ's - well.. its walmart, c'mon) She rushed after him with whatever shoes she could find by the door. While shopping, S had a hard time catching up with hubby (no wonder!) and that's when the reason was discovered!!!
